That perfectly ties with my experience. Just direct prompts, with limited setup and limited context seem to work better or just as well as complex custom GPTs. There are not just diminishing, but inverting returns to complexity in GPTs

limited prompts work well for limited programs, or already well defined and cemented source bases.

once scope creeps up you need the guardrails of a carefully crafted prompt (and pre-prompts, tool hooks, AGENTS files, the whole gambit) -- otherwise it turns into cat wrangling rapidly.

Not in our (30+ year old software company) experience and we have large code bases with a lot of scope creep ; more than ever as we can deliver a lot more for a lot less (lot more revenue / profit too).
